How can I find the build date or year of a tractor I am buying? The dealer says a tractor is not like a car, there is not a year model. I would like to know the build date. What year did the 4340c go to a digital hour meter? This tractor has a analog hr meter. I noticed the other 4340 has a digital hr meter. I just would like to know this for my own inforamtion. Thanks for any input.
